Description

Technical Field

[0001] This invention belongs to the field of medical and nursing technology, and specifically relates to a novel nasal irrigator. Background Technology

[0002] A nasal irrigator is a tool used to clean the nasal cavity. It typically uses pressure (either a bag-type nasal irrigator, a simple bottle-type irrigator using gravity, or a mechanical pressure such as an electric one) to deliver saline solution into the nostrils. The solution flows through the nasal vestibule (the part exposed outside the head), sinuses, and nasal passages, bypassing the nasopharynx, and exiting either through one nostril or the mouth. Through this pathway, the saline solution's own bactericidal properties and the force of the water flow remove accumulated pathogens and impurities from the nasal cavity, thereby restoring the nasal cavity's normal physiological environment and self-detoxification function, ultimately protecting the nasal cavity.

[0003] Existing nasal irrigators typically have the air inlet located at the bottom (see authorized patent number: CN212466559U), allowing air to enter from the bottom up. This method of air intake can cause backflow of fluid from the irrigator into the air inlet during nasal irrigation. Therefore, solving this technical problem is a pressing issue that needs to be addressed in this industry. Summary of the Invention

[0004] The purpose of this invention is to provide a novel nasal irrigator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A novel nasal irrigator includes a nasal irrigator head and a nasal irrigator body, wherein the nasal irrigator head is detachably mounted on the nasal irrigator body. The nasal irrigator includes a liquid storage chamber, an airflow channel at the bottom of the liquid storage chamber, a connection part at the bottom of the liquid storage chamber for connecting with the nasal irrigator body, an air inlet at the lower part and / or bottom of the outer wall of the liquid storage chamber, a waste liquid chamber fitted at the top of the liquid storage chamber, a water suction pipe inside the waste liquid chamber, and a first spray hole at the top of the water suction pipe. The nasal irrigator body includes a housing, an air pump installed inside the housing, a battery and a control element installed inside the housing, and the battery and control element are electrically connected to the air pump respectively; the air pump is provided with an air pump inlet and an air pump outlet; the air pump inlet is connected to the air inlet, and the air pump outlet is connected to the airflow channel.

[0006] In a preferred embodiment, a water inlet pipe is sleeved on the airflow channel, a water inlet is provided at the bottom of the water inlet pipe, and a water outlet is provided at the top of the water inlet pipe. The water inlet is connected to the liquid storage chamber, and the water outlet corresponds to the first spray hole.

[0007] In a preferred embodiment, the water suction pipe is fitted onto the water inlet pipe, and the water suction pipe extends from the inside of the waste liquid chamber.

[0008] As a preferred embodiment, a cup lid assembly is provided at the top of the waste liquid chamber, and the cup lid assembly is adapted to the water suction pipe; The cup lid assembly includes a bottom base that snaps onto the top of the waste liquid chamber. A nasal spray plug is provided on the bottom base, and a second spray hole is provided on the top of the nasal spray plug. The nasal spray plug is sleeved on the water absorption pipe, and the second spray hole corresponds to the first spray hole.

[0009] In a preferred embodiment, a return fluid hole is provided around the bottom of the nasal spray plug, the return fluid hole is connected to the waste fluid chamber below it, and an annular baffle is provided on the outer circumferential surface of the return fluid hole.

[0010] As a preferred embodiment, an air intake communication cavity is provided at the top of the housing, and the air intake communication cavity is connected to the nasal washing head through a connecting part.

[0011] In a preferred embodiment, both the air pump inlet and outlet are located on the top of the air pump, and an inlet through hole and an outlet through hole are provided on the inlet connecting cavity; the air pump inlet and outlet protrude from the inlet through hole and outlet through hole, respectively.

[0012] In a preferred embodiment, a waterproof component is provided in the air intake communication cavity; the waterproof component includes a waterproof base, which is fixedly installed in the air intake communication cavity, and a waterproof outlet corresponding to the air pump outlet and air passage is provided on the waterproof base. A waterproof cover is provided on the waterproof base, which covers the air pump inlet, and a connecting hole communicating with the air inlet and air pump inlet is provided on the side of the waterproof cover.

[0013] As a preferred embodiment, a mounting groove is provided at the bottom of the air intake communication cavity, and the waterproof base is mounted in the mounting groove.

[0014] In a preferred embodiment, a support base is installed at the bottom of the nasal irrigator body, and a support column and a mounting slot are provided on the support base. The top of the support column abuts against the bottom of the air pump, and the battery is installed in the mounting slot.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The novel nasal irrigator of this invention has an air inlet at the lower part and / or bottom of the outer wall of the liquid storage chamber. The air inlet is connected to the air pump inlet on the air pump. This method of air intake from the outer wall of the liquid storage chamber of the nasal irrigator changes the existing method of air intake from the bottom, solving the problem of backflow of liquid into the air inlet. This ensures that no backflow of liquid will flow into the air inlet during the use of the nasal irrigator, greatly reducing the failure rate of the device.

[0016] The novel nasal irrigator of this invention separates the storage chamber from the waste liquid chamber by placing the waste liquid chamber inside the storage chamber and connecting the return liquid hole to the waste liquid chamber. This prevents the return liquid from entering the storage chamber, avoids the turbulence of wastewater from the nasal irrigator after cleaning the nasal cavity, and improves the nasal irrigator effect.

[0017] The novel nasal irrigator of this invention features a hollow nasal spray plug. The nasal spray plug is fitted onto the first spray hole of the water suction pipe, aligning the first spray hole with the second spray hole. This design prevents the nasal irrigator tip from being inserted into the nostril and causing injury, thus enhancing user comfort. Furthermore, after the atomized particles of the cleaning solution are sprayed from the second spray hole of the nasal spray plug and clean the nasal cavity, these atomized particles will re-aggregate into a water flow and return to the waste liquid chamber through the return hole, thereby preventing waste liquid from entering the storage chamber.

[0018] The novel nasal irrigator of the present invention has an air pump inlet and an air pump outlet located on the top of the air pump. At the same time, a waterproof component is installed in the body of the nasal irrigator. A waterproof cover is installed on the air pump inlet, and a connecting hole is opened on the side of the waterproof cover. On the one hand, it does not affect the air intake of the nasal irrigator, and on the other hand, the waterproof cover can prevent the atomized water vapor from flowing into the air pump inlet.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Please see Figures 1-15 As shown, this embodiment of the invention provides a novel nasal irrigator, specifically including a reservoir 1 for storing cleaning fluid. An airflow channel 2 is provided at the bottom of the reservoir 1. In this embodiment, the airflow channel 2 is located in the middle of the reservoir 1, and an air outlet 9 is provided at the top of the airflow channel 2. A connecting part 4 is provided at the bottom of the reservoir 1 to connect with the nasal irrigator body 200. In this embodiment, the connecting part 4 has a threaded structure, allowing the nasal irrigator head to be detachably connected to the nasal irrigator head body 3 via a threaded connection. An air inlet 5 is provided at the lower part and / or bottom of the outer wall of the reservoir 1 (in this embodiment, the air inlet 5 is located at the bottom of the outer wall of the reservoir 1), and the air inlet 5 communicates with the cavity inside the nasal irrigator body 3. In this embodiment, air entering from the air inlet 5 is ejected through the airflow channel 2 under the action of a siphon effect, resulting in high-speed gas and atomized fluid (cleaning fluid stored in the reservoir 1) being sprayed out to clean the nasal cavity. A water inlet pipe 11 is fitted onto the airflow channel 2. A water inlet 3 is located at the bottom of the water inlet pipe 11, and a water outlet 12 is located at the top of the water inlet pipe 11. The water inlet 3 is connected to the liquid storage chamber 1, and the water outlet 12 corresponds to the first spray hole 8. A water inlet gap is provided between the water inlet pipe 11 and the airflow channel 1. Specifically, the cleaning fluid in the liquid storage chamber 1 enters the water inlet pipe 11 through the bottom water inlet 3 under the action of the suction pressure, and then sprays out from the water outlet 12 into the suction pipe 7.

[0024] Please see Figures 1-15As shown, a waste liquid chamber 6 is fitted onto the top of the storage chamber 1. A water suction pipe 7 is located inside the waste liquid chamber 6, and a first spray hole 8 is located at the top of the water suction pipe 7. The water suction pipe 7 is fitted onto the water inlet pipe 11. The waste liquid chamber 6 and the water suction pipe 7 are an integral structure, with the water suction pipe 7 tapering from bottom to top. In this embodiment, the sprayed liquid from the water outlet 12 enters the water suction pipe 7 and undergoes secondary compression and atomization, resulting in a finer mist that is sprayed from the first spray hole 8. Simultaneously, by fitting the waste liquid chamber 6 inside the storage chamber 1, the storage chamber 1 and the waste liquid chamber 6 are separated, preventing the return liquid from entering the storage chamber 1 and avoiding the turbulent flow of wastewater from the nasal rinse solution after nasal irrigation, thus improving the nasal irrigation effect. Meanwhile, the cross-sectional area of ​​the water suction pipe 7 is at least twice the cross-sectional area of ​​the airflow channel 2, and the top air outlet 9 of the airflow channel 2 is matched with the first spray hole 8, which can increase the atomization effect of the cleaning liquid.

[0025] Please see Figures 1-15 As shown, a cup lid assembly 10 is provided at the top of the waste liquid chamber 6. The cup lid assembly 10 includes a bottom base 101, which is snapped onto the top of the waste liquid chamber 6. A nasal spray plug 102 is provided on the bottom base 101, and a second spray hole 103 is provided at the top of the nasal spray plug 102. The nasal spray plug 102 is fitted onto the water absorption pipe 7, and the second spray hole 103 corresponds to the first spray hole 8. Return holes 104 are provided around the bottom of the nasal spray plug 102, and the return holes 104 communicate with the waste liquid chamber 6 below it. The return holes 104 are evenly distributed in a fan shape along the bottom circumference of the nasal spray plug 102, and an annular baffle 105 is provided on the outer circumferential surface of the return holes 104. In this embodiment, the nasal spray plug 102 is hollow inside, and the nasal spray plug 102 is fitted onto the first spray hole 8 of the water absorption pipe 7, aligning the first spray hole 8 with the second spray hole 103. The nasal spray plug 102 is designed to prevent the nasal spray nozzle from being inserted into the nostril and causing injury, thus providing greater comfort for the user. After the atomized particles of the cleaning solution are sprayed from the second spray hole 103 of the nasal spray plug 102 and clean the nasal cavity, these atomized particles will converge again into a water flow and return from the return hole 104 to the waste liquid chamber 6, thereby preventing the waste liquid from entering the storage chamber. In this embodiment, the volume of the waste liquid chamber 6 is 1 / 3 to 1 / 2 of the volume of the storage chamber 1 (in this embodiment, the volume of the waste liquid chamber 6 is 1 / 3 of the volume of the storage chamber 1), ensuring a proper fit between the two and achieving better atomization. In this embodiment, by providing an annular baffle 105 on the outer circumferential surface of the return hole 104, it is possible to prevent the waste liquid after cleaning the nasal cavity from overflowing onto the bottom base 101 and then overflowing to the outside of the cup cap assembly 10.

[0026] Please see Figures 1-15As shown, the nasal irrigator body 200 includes a housing 21, which has a hollow structure. An air pump 22, a battery 23, and a control element 24 are installed inside the housing 21. The battery 23 and control element 24 are electrically connected to the air pump 22. The battery 23 supplies power to the air pump 22 and the control element 24. The air pump 22 has an air pump inlet 25 and an air pump outlet 26. The air pump inlet 25 is connected to the air inlet 5, and the air pump outlet 26 is connected to the airflow channel 2. In this embodiment, after the control element 24 starts the air pump 3, air is introduced into the airflow channel 2 through the air pump outlet 26 of the air pump 22. Thus, the cleaning fluid in the liquid storage chamber 1 is atomized within the liquid storage chamber 1 (mainly through the water inlet pipe 11 and the water suction pipe 7), passes through the first spray hole 8, and is then sprayed out from the second spray hole 103.

[0027] Please see Figures 1-15 As shown, an air inlet cavity 27 is provided on the top of the housing 21, and the air inlet cavity 27 is connected to the nasal washer 100 via a connecting part 4. Specifically, a thread is provided on the inner wall of the air inlet cavity 27 to mate with the connecting part 4, and the connecting part (threaded structure) on the nasal washer 100 is threadedly connected to the inner wall of the air inlet cavity 27. In this embodiment, the air pump inlet port 25 and the air pump outlet port 26 are both located on the top of the air pump 22, and an air inlet through hole 271 and an air outlet through hole 272 are provided on the air inlet cavity 27, with the air pump inlet port 25 and the air pump outlet port 26 extending out from the air inlet through hole 271 and the air outlet through hole 272, respectively.

[0028] Please see Figures 1-15As shown, a waterproof component 28 is provided inside the air intake cavity 27. In this embodiment, the waterproof component 28 includes a waterproof base 281, which is fixedly installed inside the air intake cavity 27. A waterproof outlet 281 corresponding to the air pump outlet 26 and the air outlet 272 is provided on the waterproof base 281. A waterproof cover 283 is provided on the waterproof base 281, which covers the air pump inlet 25. A connecting hole 284 communicating with the air inlet 5 and the air pump inlet 25 is opened on the side of the waterproof cover 283. In this embodiment, the gas entering from the air inlet 5 enters the air pump inlet 25 through the connecting hole 284 on the side of the waterproof cover 283. After passing through the air pump 22, the gas exiting from the air pump outlet 26 enters the airflow channel 2, causing the cleaning liquid in the liquid storage chamber 1 to be atomized into particles under the action of the airflow and sprayed out from the second spray hole 103, thereby realizing the function of cleaning nasal mucus. A waterproof cover 283 is provided on the air pump inlet 25, and a connecting hole 284 is opened on the side of the waterproof cover 283. This not only does not affect the air intake of the nasal irrigator, but also prevents atomized water vapor from flowing into the air pump inlet 25 through the waterproof cover 283. In this embodiment, a locking groove 273 is provided at the bottom of the air intake connecting cavity 27, and the waterproof base 281 is locked in the locking groove 273. In this way, the waterproof component 28 can be fixed in the air intake connecting cavity 27 through the locking groove 273, preventing the waterproof component 28 from shaking in the air intake connecting cavity 27 when the nasal irrigator is in use.

[0029] Please see Figures 1-15 As shown, a support base 300 is installed at the bottom of the nasal irrigator body 200. A support column 31 and a mounting slot 32 are provided on the support base 300. The top of the support column 31 abuts against the bottom of the air pump 22 to support and fix the air pump 22. The battery 23 is installed in the mounting slot 32 for fixation.
